Abstract

A newly built vacuum ultraviolet (VUV) laser/time-of-flight mass spectrometer is described, which has been used to record the first vibrationally and rotationally resolved spectra of the E0(+) ion-pair state <--X0(+) ground state transition of jet-cooled bromine monochloride BrCl, near 145 nm. The mass resolution of the instrument (m/Delta m approximate to 1000) was sufficient to obtain single isotopomer data. Preliminary results for (BrCl)-Br-79-Cl-35 are reported. Like other interhalogens, BrCl vibronic band intensities vary widely in the VUV, presumably as a result of excited state perturbations. This scenario has beencorroborated by the observation of an irregularly spaced vibrational progression, and the irregular behavior of the excited state rotational constants as a function of upsilon'.
